what is the use of the law of proportions ?
To find the value of x in the equation, use the Law of Proportions. To use the Law of Proportions, you need to have at least three values for the equation. If you have fewer than three values, use the Law of Determinants or the Law of Cross Multiplication. If If you have fewer than three values, use the Law of Cross Multiplication or the Law of Determinants. To solve for x using the Law of Cross Multiplication, multiply the two unknown values to find the coefficient of the other variable. Then, multiply the variable x =
